Tyronn Lue thinks JR Smith has had a "great attitude" in training camp.

The 33-year-old guard struggled with the Cavaliers last season and his spot in the team's rotation is reportedly in jeopardy. But, Lue said Tuesday he has been impressed with Smith so far this preseason.

"His body of work speaks for itself," Lue said (via Cleveland.com). "He's a veteran who helped us win a championship two years ago. … He's taken on that veteran leadership role of telling the young guys how it is and what they're supposed to be doing. He's been leading by example."

Lue said Smith reported to training camp "15 pounds" lighter.

"I think as you get older, (it) helps with the wear and tear on your body," Lue said. "The lighter you are, the better it is for your body. Being in shape the way he came in is phenomenal."

The 14-year veteran has been with the Cavaliers since January 2015. He averaged 8.3 points and shot 37.5 percent from 3-point range last season.
